What authority does the COR have regarding travel costs?

The correct choice emphasizes that the Contracting Officer's Representative (COR) has the ability to authorize travel costs for specific identified travel related to the contract. This authority typically means that the COR can review and approve travel requests that align with the terms of the contract, ensuring that the costs are reasonable, necessary, and within the scope of the work being performed.

This responsibility is crucial as it allows the COR to manage and oversee costs incurred during the execution of the contract. By approving specific travel-related expenses, the COR helps maintain budget adherence and ensures compliance with the established travel policies and guidelines, while supporting the contractor's ability to successfully carry out the contracted activities.

In contrast, the other choices would imply either unrestricted or no authority over travel costs, or limited approval authority solely by the Contracting Officer. However, it is the COR's role to act as a key liaison between the contractor and the government, allowing for practical fiscal oversight within designated parameters.
